I don't know how to simplify this:

4ab^2(-3a^2b)^2/ (-2ab)^3

Just apply the laws of exponents. When you multiply exponent terms, you add the exponents. When you divide, you subtract the exponents.





Now, you try finishing. Remember the rule about dividing exponents... subtract the exponents. Just make sure you keep like terms together. That is, you can't divide . Keep the a's with the a's and the b's with the b's.

ohhh.
so would the answer be 4.5a^2b ?

Yes, it would. :)

Except you forgot a negative. Perhaps write the 4.5 as 9/2

Good work. See, you can do it.
